Abstract:The ultrasound irradiation and simultaneous oxygen bubbling into the L-ascorbic acid aqueous solution has been studied in order to establish a cost-effective oxidation process for wastewater treatment. The application of ultrasound considerably increases the decomposition rate, while the relative chemical oxygen demand (COD) value is essentially unchanged. The influence of various process parameters, such as temperature and oxygen flow rate, has been studied. Moreover, we have carried out preliminary experimen… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
